IMPROVEMENT IN TURN-TABLES.

Specification forming partmf Letters Patent No. 219,152, dated September 2, 1879 application filed June 28, 1879:

To all whom "it may concern:

Be it known that I, CHARLES PETER DUREL, a resident of the city of New Orleans, parish of Orleans, and State of Louisiana, have in vented a certain new and useful Improvement in Railway Turn-Tables; and I do hereby declare the following to be a full, clear, and correct description of the same, reference being had to the annexed drawings, making a part of this specification.

This invention has for its object the transfer of cars from one track to another by means of a turn-table on the surface of which is constructed any desired number of tracks.

Figure 1 is a top view or plan of my invention 5 Fig. 2, a section through the line 4 00 thereof; and Fig. 3 shows a means for stopping the table at any desired turnout.

On the drawings but four tracks are shown; but it is evident that any desired number may be employed with equally as good results.

A is a circular pit, in the center of which is erected a similarly-shaped standard, B, having a pawl, c, pivoted in the top thereof, as shown. D is the turntable proper. Its under side is providedwith several pairs of lugs, between each of which is'journaled a roller, as at e.

In the center of' the table is a circular opening the diameter of which is slightly greater than that of the central standard, B, around which it is designed to be operated. Arecess is constructed in the upper side of the table, around the opening therein, and in this recess is formed ratchet-teeth g, the number of which is made tocorrespond with the track entrances or exits.

The pawl 0 operates over these ratchets, and allows the table to be turned in but one direction. The aforesaid recess is provided with a cover, h, to exclude dirt therefrom, and the said cover is pinned to the central standard and furnishedwith a sliding or hinged piece, 2', the opening of which will give access to the pawl should the same at any time become out of order. On the under side of the table, and near its outer edges, are secured a number of triangular lugs, k, corresponding in requisite position,'it also readily admits, under v a slight pressure, of its position being changed to accommodate any other line of cars.

On one side of each track a bumper-block is secured, as at c, and the cars traveling over said tracks are each provided with devices such as are shown in Fig. 3, and which consist of an elevating-standard, P, the lower end of which is provided with a shoe, q, which, when brought in contact with one of the bumpers,

stops the table immediately on a line with an exit-track.

This table is turned by the animal attached to the car, or by the driver or other person pushing the head of the car around in the direction required.

Having described my invention, What I claim, and desire to secure by Letters Patent, is-

1. A turn-table furnished with two or more sets of tracks, and with a recess in which are constructed ratchet-teeth g, which are engaged by a pawl, c, that is pivoted to a central standard, B, as described, and for the purpose set forth.

2. In combination with a turn-table provided 'with lugs 10, a pivoted lever, L, the latter held.

in position against a limited pressure by a spring, a, as described, and for the purpose specified.

In testimony whereofl have hereunto signed my-name.
